Product details

Description

The MAX1954A synchronous current-mode, pulsewidth modulation (PWM) buck controller is pin compatible with the popular MAX1954 and is suitable for applications where cost and size are critical.

The MAX1954A operates from an input voltage range of 3.0V to 13.2V, independent of the IC supply.

Features

foldback current limiting that greatly reduces input current and component power dissipation during output overload or short-circuit conditions. The compensation and shutdown control (COMP) input, in addition to providing compensation to the error amplifier, can be pulled low to shut down the converter. An input undervoltage lockout is provided to ensure proper operation during power sags to prevent the external power MOSFETs from overheating. Internal digital soft-start is included to reduce in.
